Question

我正在尝试用OpenGL编程。

所以写了一个测试程序调用t_gl1.cpp

我用

成功构建了它

$ g ++ t_gl1.cpp -lglut -lGL -lGLU -o t_gl1

没有任何错误。

然而，如果我尝试运行它，我得到了

freeglut（./t_gl1）：错误：函数fgOpenWindow中的内部错误 X请求失败的错误：BadWindow（Window参数无效）失败请求的主要操作码：4（X_DestroyWindow）失败请求中的资源ID：0x0 失败请求的序列号：26 输出流中的当前序列号：29

有人知道发生了什么吗？

以下是在Windows和Mac上测试的代码，没问题。但无法让它在Fedora和Ubuntu上运行

我与爪子合作。这是因为Nvidia的问题。我找不到在Fedora 15上安装Nvidia开发者驱动程序的官方方法。所以我使用了rpmfusion。驱动程序运行，我可以运行CUDA。只有GLX相关的东西搞砸了。然而，它也搞砸了Gnome 3。

所以我切换到Arch Linux。有了一个非常干净的开始，安装Nvida并根据ArchWiki安装Xorg。然后安装Gnome。令人惊讶的是，OpenGL可以工作。我想Arch repo中的驱动程序不是开发人员的驱动程序。也许只是为显示驱动程序。但是，CUDA可以工作。

我很高兴。希望这对其他想要在Linux上运行CUDA和OpenGL的人有所帮助。

谢谢，阿尔弗雷德

Answer 2

代码没有问题。我可以使用NVIDIA版本280.13驱动程序在正确配置的64位Linux系统上成功编译和运行它。您有驱动程序或X11驱动程序安装或配置问题。此问题无需编程帮助。

Answer 3

由于您标记了此问题cuda，我将假设您正在运行NVidia硬件。

尝试installing some drivers。
